    Did They RAT Sand?

    From Opportunity on Sol 236:

    I haven't been keeping up lately, but I do know that a pebble got stuck in the rat mechanism, so I wouldn't be surprised if they stuck it in the sand while trying to clear it.

    Please try to keep up LOL :P :P

    The pebble fell out by itself several weeks ago. It looks like a depression from one of the spectrometers placed in the soil/dust.

    According to the latest flight directors update they drove to a rock called "ork" ?

    That picture is proof of life on Mars. Behold the elusive Martian Sand RAT! :wink:

    Boy it's great to start seeing some new images again. Does anyone know when they're going to crawl out of that crater and head for the etched terrain down south?

    They RAT'd sand. Well, at least they brushed it. Apparently they wanted to characterize the dunes, and took the IDD tools and intruments to an accumulation of sand.

    Planetary Society MER Update, September 23

    Next on her agenda is the examination of some sand that appears to have been blown up from the artfully rippled dunes on the bottom of the crater and piled up against a rock the team has dubbed Ellesmere. "Since we weren't able to safely drive into the dunes because our wheels could get stuck -- and because the sand looks interesting, we found a place where the sand has piled up in a small area next to this rock," Crisp explained. "We want to carefully document the properties of that sand pile. The idea is to even use a rock abrasion tool (RAT) brush to kind of dust off this dune material to really characterize the inner material with mini-TES and Pan Cam, and the Mössbauer spectrometer."
